I have late-'80s cheap steel ramps which I hardly ever use, because they're too high for oil changes and have braces that must be bolted on for use, then removed afterward to get them back into the box for storage. For oil changes, I use short 2×6's as ramps, supported on one end by a solid oak block on the uphill (right) side of the car, and a slightly taller concrete hunk on the low (left) side. That way, the car body ends up approximately level, despite being on a hill. Another short 2×6 flat on the ground at the bottom of each inclined 2×6 solves the problem of the car body hitting the ramp ahead of the wheel.
Extra-low factory-made ramps might be less cumbersome, but seem to be scarce. None of my previous cars required ramps or jacking for oil changes, so having to lift the car now is an annoying inconvenience.
